Correct Answer - Option 3 : 3 : 2

**Given:**

Ratio of milk and water in 3 different samples are 4 : 1, 3 : 2 and 2 : 3

**Formula ** **Used:**

Simple Concept of Ratios

**Calculation:**

Proportion of milk in 3 samples is 4/5, 3/5 and 2/5

Proportion of water in 3 samples is 1/5, 2/5 and 3/5

Since equal quantities are taken,

Total proportion of milk = 4/5 + 3/5 + 2/5 = 9/5

Total proportion of water = 1/5 + 2/5 + 3/5 = 6/5

Proportion of milk and water in the solution = 9/5 + 6/5 = 9/6 = 3/2 = 3 : 2

**∴ The required proportion is 3 : 2.**
